🔺11 - Moment of a Force about a Point 2D Examples 1 - 3

​ ​🔺11 - Moment of a Force about a Point 2D Examples 1 - 3

In this video we are going to learn how to learn how to determine the moment or resultant moment of forces about a point.

Moment of a force about a point O is the force times the perpendicular distance from O or the axis containing O to the line of action of the force
Mo = Force * perpendicular distance (Nm)
Moment can be taken in the clockwise or anti-clockwise direction.

We shall solve three examples in this video.

00:00 - Moment of a force
06:58 - Example 1
12:30 - Example 2
18:47 - Example 3

Incredible video, hats off to you for providing the examples and making clear and thorough steps to reach the final answer. Please keep making videos, thank you!

[henhan]

thank you so much, sir! Hopefully I get good scores for my quiz tomorrow

[NANOR_OB]

Thank you for this one ...I'm gonna ace this midsem 🔥🔥🔥🔥

[appledestroyer]

It is a very good video, very concise and informative. Most importantly, it is reliable.

[EdisonKruger-bx]

Thank you so much this video made huge difference, however id like to know whether we should consider the signs when finding the components of each fore eg for the last question we solved, why wasnt the F2y component -519.62, or do we just ignore the directions since we are working with moments ????

[samarbader]

Absolutely amazing, I hope get 100 in this course

[hannahs.opigan]

Thank you so much! This is a great help for me!😭❤️

[SaddySimwinga-rnvj]

Thanks 👍 so much... I have enjoyed it🎉🎉

good morning sir i was just wondering about signs of the moment, my teacher told me clockwise is negative but right now i m confused i would like to know if there is some exception or something like that . thank you and have a nice day.

[jeremytan-ii]

in your last example sir the force in f2y is directly downward so your sign of your force in f2y should be negative (-600sin(60))

[hbasyraff]

anti-clockwise shoould be positive right?if i'm not mistaken

[MarkMullings-th]

Well done sir. However for question 2 am wondering why the 500N isn’t sin45 when finding the distance, because it would be opposite to the angle and cos45 for 300N

[vicky]

Hello, please how do u know whether the direction for the forces should be clockwise or anticlockwise

[samahazard]

Wawooo ❤ explanation is clear here, hope everybody could explain like u

[FatawYakubu-]

Please does it mean that for the upward force the direction is anti clockwise and for the downward force the direction is clockwise

[Hola-txfr]

Hi teacher, thank you so much for your efforts. I just want to understand why in the second exercise, we did not project the forces onto the x and y axes like we did in the first and last examples.

[keptstudioL]

please explain why you say that F1x corresponds with 4 and F1 corresponds with 5.

[magdalenapovanhu]

How do you know if the force is in the clockwise or anti clockwise moment??

[ioriyagami]

Hey sir Good afternoon do you have some videos related to this?

[michaelasilidjoe]

From the last eg. I didn't understand why you multiplied the f1x by 0.25
